  • a Overall includes dinucleotide repeats, other repeats, and seven SSRs with unknown repeat core sequences.

  • The average amounts of allele and gene diversity in teosinte and maize are reported for dinucleotide repeats, for the other repeats, and all the SSRs together with the standard errors in parentheses. The relative losses of diversity in the number of alleles (Δallele) and in gene diversity (ΔGD) are also calculated (see text for details).
